Portugal has begun voting in the first round of a presidential election in which a far-right candidate could, for the first time, make it to a run-off, possibly securing another win for Europe's burgeoning far-right parties. Polling stations opened at 8am local time (08:00 GMT) on Sunday across the country, and exit poll results will be announced 12 hours later. Almost 11 million people are eligible to vote in the election, which has 11 candidates.
